REPAIRMTOOL..

SPECIFICATION forming part of Letters Batent No. 691,055, dated January 14, 1902-. Applioationled May 6,1901. Serial No. 58,993. (No model.)

T all whom it may concern.-

Be it known that I, FRANKLIN HOOVER, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Repair-Tools, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention has reference to a tool capable of use in repairing or tuning pianos, and

particularly designed for extracting the hammer-Shanks from the portion of the piano in which they are usually socketed or for removing the hammer from its shank.

The invention consists in the peculiar construction of a tool and in the novel arrangement of i-ts parts.

In the drawings, Figure l is a perspective View of a repair-tool embodying my invention; and Fig. 2 is a vertical central section therethrough, the tool being shown in operative position relative to the piano-hammer that is to be removed from its shank.

In construction the tool comprises two pivoted clamping members A and B, provided, respectively, with the handle-sections D and C. The members, as shown, are further pro-l vided with the liat-faced jaws c and b and intermediate the latter and the pivotpin c with the concave jaws d and e.

E designates a lever fulcrumed upon the clamping members and provided with the bifurcated end or claw F, the latter being so proportioned and arranged as to bring the opening between the claw members into coincidence with the concave jaws, as illustrated in Fig. 1. The opposite end of the lever, as shown, extends rearwardly between the handle-sections and is preferably provided with astop'pin G, which limits the swinging movement of the lever.

While the lever may be fulcrumed upon the clamping members in numerous ways, I prefer to pivot the lever to the members in the manner indicated in Fig. 1, the pivot-pin c for the members being used for this purpose. The concave jaws are also threaded, as indicated in Fig. l, so as to produce a roughened surface, that will enable the tool to more effectively grip the shank to be extracted.

In use the tool may be applied to the shank as indicated in Fig. 2, the shank being gripped between the concave jaws in such a position that the lever will be in its depressed position, with the claw or forked end engaging beneath the hammer. It will be obvious that upon depressing the lever while the shank is clamped between the jaws the latter will be withdrawn from its socket in the hammer. It will also be observed that by providing the flat-faced jaws for the clamping members the tool may be used, if desired, as ordinary pliers.

What I claim as my invention isl. In a repair-tool, the combination of two concaved jaws pivoted to each other and each having a handle-section integral therewith, and a lever fulcrumed upon the handle-sections having a forked end or claw extending into operative relation to the jaws.

2. In a repair-tool, the combination of two concaved jaws each having a handle-section integral therewith, of a lever fulcrumed upon the handle sections and provided with a forked end or claw extending into operative relation with the jaws, and a single pivot-pin connecting the handle-sections and lever, substantially as described.

3. In a repair-tool, the combination with two pivoted concaved jaws each having a handle-section integral therewith, of a lever fuli crumed upon the handle-sections having a forked end or claw extending into operative relation with the jaws, and a stop-pin depending from and limiting the lateral swinging movement of the lever.

In testimony whereof I affix my signature in presence of two witnesses.

FRANKLIN HOOVER.
